The BZY93C18 is a Zener diode from Solid State Devices Inc (SSDI) designed for voltage regulation and protection applications. It features a nominal Zener voltage of 18V with a tolerance of ±6.39%, a maximum power dissipation of 20W, and a maximum impedance of 1.5Ω. The device has a maximum reverse leakage current of 50µA at 12V and can operate at a junction temperature up to 175°C.
This diode is housed in a DO-203AA (DO-4) stud mount package, which provides robust mechanical mounting and efficient heat dissipation for high-power applications. The stud mount design allows for secure attachment to a heatsink, making it suitable for industrial and power supply circuits where reliable voltage clamping is required.
Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in power supplies, motor drives, and other high-current circuits. The combination of high power rating and low impedance ensures stable operation under varying load conditions.
